Agreed for deletion, it's irreparably broken, I would need to create from scratch a new GDAL legacy package to be able to run in parallel with the current version, and that would easily go down the rabbit hole of unmatched dependencies. My last attempts to force Python 2 in recent GDAL gave me too many segfaults to be useful.
Since this is a dependency for python2-arcsi, the same should be said about that package. I'm going to disown these two now.
MarsSeed [1] filed a deletion request for python2-rsgislib [2]:
Quite irreparably broken, deprecated Python2 library.
Last updated in 2018; source is now 404.
Missing the undeclared boost-python2 and python2-gdal dependencies.
Its core binary dependency GDAL no longer supports Python2 bindings.
And for the old Python2 bindings in AUR, there is no matching GDAL
build.
I recommend deleting this defunct package.
Finally it seems the Python3 version of the arcsi toolkit and its
Python dependencies, available on AUR, have caught up with each other
and with the current version of gdal in repo.
